Wireless Audio Module Design

We need a low-latency wireless audio system that we can integrate into existing products, but to start with it will be a stand-alone product (plug-in transceivers). You would be designing this product - to include PCB, housing, and firmware. We can take care of other things like the mounting pieces, case, etc if needed. Our current engineers are too busy with other projects, we could really use some help with this wireless audio system!

The application of this system is to connect a metal detector to a set of wireless headphones. Low-latency (under 40ms) is key, as are durability, ease of use, and as always, cost. This is our first time using [url removed, login to view], but we look forward to forming long-lasting relationships with the people we work with.
